Colour mode must be CMYK (NOT RGB). Files supplied as RGB may not be detected and will print discoloured and dull.
Colour and Grayscale raster images should be 300dpi, (350dpi max) Monochrome (bitmaps) should be 600dpi (1 00dpi max).
PLEASE NOTE: Lower dpi values will result in a pixelated, low quality image. Higher dpi values increase file size, processing time and ink density without any real quality benefits.
Paths Output Resolution (vector/linework/ curves) = 800dpi minimum (usually set in preferences). Any settings lower than this value will result in loss of points and jaggedness in vector paths.
When supplying (PDF) files make sure that all fonts are embedded. If you are not supplying a (PDF) file you MUST supply all fonts. When converting type to paths/outlines/curves, remember that stray points still contain fonts. These stray points need to be deleted.
We require at least 3mm external bleed – anything that touches a trim edge must be extended at least 3mm past it.
We recommend a 3mm internal bleed or type area – we recommend you keep all important information at least 3mm in from the trim
There is no need to manually trap any files as all vector elements are auto-trapped in our RIP process, and raster files are not affected.
We recommend that you supply hard copy laser or high quality inkjet prints when supplying print ready files to ensure files are viewed accurately. When supplying multiple page books we recommend a page layout dummy is supplied.
Check spine width with our production department on perfect bound, burst bound and section sewn cover books.
Creep is the shifting position of the page in a saddle-stitched bound document. Creep moves the inside pages away from the spine of the collated document.
All books and brochures use a sheet that is folded to create separate page areas. Because the sheet itself has some thickness (however small), each fold causes a very small incremental shift in the location of the edge of each page relative to the other pages. The result is that the edges of pages furthest from the saddle’s innermost fold seem to move away from the edges of pages closest to the innermost fold. As the number of pages in the saddle increases, so does the amount of this shift. To counteract the effects of this shift, the bindery trims the edges of the finished book to a common edge.
Trimming the bound pages resolves only part of the problem, however, as the edges of pages move, so do the content areas imaged on them. The apparent shift of content area caused by folding a sheet multiple times is known as creep or binder’s creep. The effect of creep is that the content area of pages closer to the innermost fold in a saddle appear to move towards the outer margins of the page.
Creep becomes more noticeable as the number of sheets in a saddle increases, and its effect is most noticeable on pages farthest from the center fold of the saddle. Consequently, a book layout must also specify the number of sheets in each saddle because the number of sheets in each saddle affects the amount of creep that needs to be accounted for.
If you are using a new cutting forme, please supply in the same document as a 0.35pt PMS spot colour set to overprint. Many standard cutting formes are available from our Production Department. Please contact our Sales Department for further information.
